Question

Write the prototype of a function called volumeOfCone that calculates and returns the volume of a cone:

Answer 1

Ans)C++ code:

#include <cmath>
#include <iostream>
using namespace std;
double volumeOfCone(double, double);
int main( )
{
//Declare variables and constants
double radiusOfCone = 0.0;
double heightOfCone = 0.0;
//Prompt the user for inputs
cout << "Enter the radius of the cone: ";
cin >> radiusOfCone;
cout << "Enter the height of the cone: ";
cin >> heightOfCone;
cout << "The volume of your cone is: " << volumeOfCone(radiusOfCone, heightOfCone) << endl;//Call the function and Display the result
system("pause");
return 0;
} //end of main

double volumeOfCone(double radiusOfCone, double heightOfCone) //function that calculates and returns the volume of a cone
{
double PI = acos(-1.0); //initializing value of PI
double volume = radiusOfCone * radiusOfCone * heightOfCone * PI / 3.0;//valculating the volume of a cone
return volume;// returning the volume
}

output:

Enter the radius of the cone:5 Enter the height of the cone: 10 The volume of your cone is: 261.799
